This variant is for use with the stratospheric-ozone-only experiment, hist-stratO3, of the Detection and Attribution MIP (DAMIP). Ozone in the troposphere, defined as grid-points having a pressure greater than 65 hPa and an ozone volume mixing ratio less than 100 ppbv in the pre-industrial control ozone field, are held at the pre-industrial values for each month of the year. Values at other grid-points evolve as in the original, transient ozone field. See Gillett et al., Geosci.
